Coolant leak

Hi, Dave here helping on RepairPal since 2010. If you have "no puddles" how do you know you have a leak? Has a pressure test been performed on your cooling system? Either it's leaking or it's not. Hands on testing - visual - along with a pressure test - is needed to find out what is going on. Reach out to a RepairPal Certified shop near you if needed for further guidance!
